OO prior to 1.0 was terribly slow at displaying the icons in the
load/save dialog window, what version of OO do you have?

Do you recommend running OO locally on a P100???? Remeber that these
machines exclusively has expensive 72-pin RAM and most of them
probably have 32 Mb of RAM or less.

Why would a faster workstation help, when the performance is bad
especially during save/load operations in openoffice? These operations
involve almost no screen redrawing so the clients will not have any
trouble in that situation.

Yes, so the obvious test of the LTSP system is: how does load/save
operations work when done on the SERVER? If, and only if, it is fast on the
server and slow on the clients there can be something to gain on
running the app locally.

And you suggest running OO locally and trying "a faster
workstation"??? What's thin about that?
